First post here so don't laugh if it is stupid obvious, loving the forum picking up tons of info. I have searched this and sort of found some answers but was hoping to get a bit more help. I have a couple of service business, we target many different towns (rural spread out area, so keywords are "my service my city") I have one main domain that ranks fairly well in each city, I then have multiple domains targeting that are EMDs for the different cities. As of right now I use mostly reseller posts on public networks to rank the main site (haven't gotten a penalty yet) I am a bit less cautious with the individual city EMDs and tend to use more comments forum sigs etc for those. I would like to set up basically a three tiered setup were I have something that basically takes all the spam and then links to the individual city EMD's. These in turn link to my main domain and I get a double benefit from them. I was curious what should I use for this third tier? I am considering buying more domains with unique ips and setting them up as blogs to take the brunt of whatever spam i can dream up. I know you guys know this 100 times better than I do, so I was just hoping to get a bit of input on whether this would be a waste of money/time. Any help at all would be very much appreciated.
